Eaton 9SX 2000VA 1800W 120V Online Double-Conversion UPS

The Eaton 9SX 2000VA 1800W 120V Online Double-Conversion UPS delivers clean, continuous power to your critical equipment, protecting servers, networking gear, and workstations from outages, surges, and data-loss events. Built for reliability in demanding environments, this compact tower UPS combines a true online double-conversion topology with generous outlet configuration and expandable runtime options. It’s designed to keep essential systems running smoothly even during severe voltage fluctuations, making it an ideal choice for small data centers, IT closets, and business-critical equipment in office or industrial settings.

• True online, double-conversion protection: The 9SX continuously converts incoming AC to DC and then regenerates a clean, regulated sine-wave AC output. This eliminates input irregularities, isolates connected equipment from brownouts and transients, and provides near-zero transfer time during power events, so your servers and storage stay online without interruption.
• High-capacity, 120V performance: With a rating of 2000 VA / 1800 W and a standard 120V output, this UPS powers critical devices with steady voltage and reliable surge suppression. Its scalable design supports sensitive electronics, network gear, and essential peripherals, giving you peace of mind during peak load conditions.
• Versatile outlet configuration: The unit features six NEMA 5-20R outlets plus one L5-20R outlet, providing flexible, code-compliant connections for multiple devices. Place your servers, switches, NAS, and other peripherals on dedicated protected circuits while leaving room for essential peripherals that require different plug types.
• Extended Run and modular upgrades: Engineered for longer runtimes, the Eaton 9SX supports Extended Run configurations with external battery modules (EBMs). This capability lets you tailor runtime to your workload, giving you valuable buffer during outages and graceful shutdowns for critical systems.
• Cybersecure network management option: Opt for the Cybersecure Network Card to monitor, manage, and control the UPS remotely. This feature enables secure access for asset management, automated notifications, and integration with centralized IT monitoring tools, all while preserving the integrity of your critical network infrastructure.
